What is the top boost a stock internal 3sgte can handle.. nevermind fuel system or anything.. just wondering what the highest number is that someone has run.. reliably and to the death... obviously running a turbo capable of the number w/o blowing hot air...
I'm just curious cuz I see some of these 4g evo motors and what not.. my friend is all hyped up on mitsu crap.. and I see these dyno pulls at 30psi and this one at 44psi.. so I was just wondering if there is a limit to what the engine can handle pressure wise w/ stock setup or if it all just comes down to horsepower output..? I ran around on 19psi all day on thursday with out an issue.. on stock fuel.. 93oct. .. no knock all day.. can't wait to hit the dyno. -------------------- 87 4runner DLX 22re, 5spd, 4.30gr, 4" lift, 30" tires, HID w/ Projectors, 6spkr + sub, custom exhaust, 94 celica leather seats, SR5 gauge cluster and clinometer. Future engine swap... possibly a 2jzge.

Short answer is a lot!
Boost alone won't kill the engine. Detonation, power output, oil starving are the most concerns. If you have ways to control them, you can boost as much as you want. Think about doing a compression check on your engine. It withstands 170 psi without blowing the HG. But a single bad knock can destroy the HG. -------------------- _Gary
